Dr. MartensWomen's Women's Clarissa II Quad Sandals

Please help me I am fighting with my wife to find thicker foot bed sandal for a man. Suggestions for a man? She hates this one .

Are these US sizes??

Would you say the sandals are kind of heavy?

I’m a 7.5-8 in most shoes, a 7 in DM boots and 8 in DM 8065 mary janes. My foot is kind of wide, should I stick with a 7 instead of sizing down?
